Seismic analysis is critical in ensuring the structural safety and performance of multistorey buildings in earthquake-prone regions. National seismic codes, such as India’s IS 1893:2016, China’s GB 50011-2010 (updated in 2016), and Turkey’s Turkish Earthquake Code 2018, play a pivotal role in guiding the design and construction of these structures. This review paper aims to compare the provisions and applications of these three seismic codes with a focus on their treatment of seismic hazards, structural response parameters, and design methodologies. Using STAAD.Pro software as a computational tool, the study identifies key differences in base shear calculations, story drift limits, ductility requirements, and material considerations. While the Indian code emphasizes simplicity and accessibility, it lacks the detailed performance-based approach of the Chinese code, which integrates advanced probabilistic hazard assessments and material guidelines. The Turkish code offers a balance between safety and economy, incorporating rigorous site-specific data and soil-structure interaction considerations. The findings suggest that aligning global seismic standards and adopting advanced computational tools can significantly enhance the design efficiency and safety of multistorey buildings. This review contributes to the broader knowledge base of seismic engineering and provides insights for improving code practices in regions with diverse seismic risks.
I. INTRODUCTION
The increasing prevalence of multistorey buildings in urban landscapes has underscored the need for robust seismic analysis to ensure their safety and resilience in earthquake-prone regions. Multistorey buildings, due to their significant height and slenderness, are particularly susceptible to seismic forces, making their design and analysis a critical aspect of structural engineering (Bachmann, 2002).
Seismic codes, which serve as regulatory frameworks for building design, vary significantly across countries, reflecting local seismic risks, construction practices, and available technology. Among the widely adopted codes, the Indian Standard IS 1893:2016, the Chinese GB 50011-2010 (updated in 2016), and the Turkish Earthquake Code 2018 are particularly prominent for their detailed guidelines on seismic design.
India's IS 1893:2016 is tailored to the country’s unique seismic zones, with a focus on practical design methodologies and material specifications suitable for local construction practices (Bureau of Indian Standards, 2016). However, it is often criticized for its limited scope in addressing advanced performance-based design and soil-structure interaction effects. On the other hand, China's GB 50011-2010 incorporates probabilistic seismic hazard analysis, offering a more detailed approach to seismic design that accounts for varying site conditions and structural complexities. Similarly, the Turkish Earthquake Code 2018 emphasizes a balanced approach, integrating both deterministic and probabilistic analyses with rigorous requirements for ductility and base isolation techniques.
This paper aims to review and compare the key provisions of the Indian, Chinese, and Turkish seismic codes, focusing on their impact on the design and safety of multistorey buildings. By leveraging STAAD.Pro software for detailed analysis, this review seeks to provide insights into the strengths and limitations of these codes and their implications for global seismic design practices. The findings are expected to contribute to the ongoing discussion to align seismic standards and advancing the resilience of multistorey buildings in earthquake-prone regions.
II. LITERATURE REVIEWS
The comparative seismic analysis of multistorey buildings as per the Indian (IS 1893:2016), Chinese (GB 50011-2010), and Turkish Earthquake Code (2018) reveals significant insights into the diversity of seismic design approaches. Each code has been developed considering the unique geological and seismic risks of its respective region, emphasizing different aspects of safety, structural integrity, and performance under earthquake conditions. The Indian code provides a well-structured framework with a focus on zoning, soil classification, and ductility provisions tailored for varied seismic risks across the country. Its approach is balanced, offering simplicity for smaller structures and advanced analysis for more complex buildings. The Chinese code emphasizes precise calculations and stricter controls for structural performance, with detailed classifications for soil and seismic intensity. This code incorporates a strong focus on time-history analysis and performance-based design, ensuring that tall buildings can withstand dynamic seismic forces effectively. The Turkish code demonstrates the highest level of detail and rigor, reflecting the country\'s exposure to frequent and intense seismic activity. Its stringent requirements for ductility, drift limitations, and seismic detailing, combined with mandatory dynamic analyses, set a benchmark for seismic design practices. In conclusion, while all three codes aim to ensure safety and performance during seismic events, their approaches vary significantly. Indian codes are versatile, Chinese codes emphasize precision, and Turkish codes adopt a conservative, cautious approach. This comparison underscores the importance of localized design strategies and continuous advancements in seismic engineering to protect life and infrastructure in earthquake-prone regions.
